God's sudden judgment of the wicked and its result

Psalm 64 chiefly speaks of the unceasing crafty hatred of the
enemy and cries to God: God will shoot at them suddenly. The
result of this judgment will be that all shall fear and declare
the work of God, for they shall wisely consider of His doing. Then
(for judgment is now come) the righteous shall be glad in Jehovah,
for His covenant name is now taken, the judgment having removed
the power of evil. The upright in heart glory. Thus judgment
introduces the millennium.
